Blender 2.8 Displacement node not working
The displacement is too weak, you're seeing it in the others because of the scale of the object.
Apply the scale (alt+A) in any mesh that it worked that you will see that the displacement effect is gone.
In the same way, press S+Z in the mesh of the pic and you will see the displacement
And you also need to be in Cycles &quot;rendered&quot; view to see it. The Shading preview will always use Eevee
